Depending on the location of the tumor, surgical procedures include right hemicolectomy, left hemicolectomy, etc. No matter which resection method is used, approximately 60 to 70cm of intestinal tube must be removed, so that the length of the colon is about half of its original length. The main functions of the colon What is it? Concentrating feces and reabsorbing it will inevitably weaken after surgery, and diarrhea may occur.
Adjuvant chemotherapy toxic side effectsStage I colon cancer does not require adjuvant chemotherapy, stage II colon cancer has high-risk factors and low expression of microsatellite instability, and stage III and IV patients must require adjuvant chemotherapy after surgery.
The auxiliary platinum agents and fluorouracil drugs have toxic side effects of diarrhea. If the patient is not suitable for using "tecan" drugs, diarrhea will also be very serious.
Indigestion, gastrointestinal disordersSome patients may also suffer from diarrhea after surgery due to physical weakness, indigestion, and gastrointestinal disorders resulting in increased stool frequency, or gastroenteritis or enteritis.
